Hi, This series includes some pieces of fixes to complete the GK20A power on/off sequences and add the suspend/resume support. The patches 1/11 - 4/11 are based on the linux-next-20141219. The patches 5/11 - 11/11 are based on the branch "linux-3.19" of Ben Skeggs's tree (http://cgit.freedesktop.org/~darktama/nouveau). Thanks, Vince Vince Hsu (4): (linux-next-20141219) ARM:

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. This version is mostly identical to v2 but fixes an important issue: the drvdata must be set to the drm_device for sysfs to work, so the platform device structure now includes the

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. Thanks to the input received for v1, this version is more self-contained and shares less stuff between nouveau_drm and nouveau_platform. The major change is that nouveau_platform is now

This patch series is the final (?) step towards the initial support of GK20A, allowing it to be probed and used (currently at a very slow speed, and for offscreen rendering only) on the Jetson TK1 and Venice 2 boards. The main piece if the first patch which adds platform devices probing support to Nouveau. There are probably lots of things that need to be discussed about it, e.g.: * The way the

Changes since v3: - Use a single dma_attr for all DMA-API allocations in instmem instead of one per allocation - Use device.info.ram_size instead of pfb->ram to check whether VRAM is present outside of nvkm Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into

Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to, and can trick

A series I have waited too long to submit, and the recent refactoring made me pay the price of my perfectionism, so here are the features that are at least completed Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to,

Thanks Ilia for the v2 review! Here is the v3 of this IOMMU support for GK20A series. Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c.
